YQ wm ATTORNEY Patented Sept. 22, 1931 UNITED STATES PATENT OFFICE JOHN ALFRED STEIN, OF NEW YORK, N. Y., ASSIGNOR TO AMERICAN MACHINE & FOUNDRY COMPANY, A CORPORATION OF NEW JERSEY DOUBLE BELT CIGARETTE COLLECTOR Application filed. May 28,

This-invention relates to cigarette collectors for continuous rod cigarette machines, and particularly to a-collector for use with high speed machines of this type.

\Vith the old slow speed machines, the cigarettes were collected by merely stopping them against a transverse wall as they came out of the machine, from which a crosswise belt carried them away. With the development of high speed machines from which cigarettes are delivered at the rate of 1200 to 1800 or more a minute at speeds of 330 to 450 or more feet per minute, this method has been found impractical, for the reasons among others that it results in injury to the ends of the cigarettes and also results in more or less uneven grouping due to erratic rebounding of the cigarettes.

The principal object of the present invention is to avoid such difiiculties. To this end it is an object of the invention to provide means for reducing the speed of the cigarettes and forwarding the cigarettes at reduced speed. Still. another object of the invention is to provide a cigarette collector which will group tipped cigarettes such as the well known .cork tipped cigarettes, which ordinarily emerge from the cutoff with the tipped ends of alternate cigarettes adjacent each other, so that only cigarettes I having their tips facing the same way will be grouped together.

Other ohjectsvare to produce a cigarette collector which will be reliable and efficient in operation over a wide range of cigarette machine speeds, including what according to presentstandards are very high speeds.

With these and other objects in View, the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically pointed out in the claims. 1

In the accompanying drawings which form a part of this specification and in which like characters of reference indicate the same or like parts:

Fig. 2 is a side elevation, partly broken away, of the device shown in Fig. 1;

Fig.4 is a sectional view taken on the line 44 of Fig. l; and

Fig. 5 is a sectional view taken on the line 55 of Fig. 2.

In carrying the invention into effect, there is provided mechanism for seizing cigarettes as they emerge from the cutoff of the cigarette machine and forwarding them at a given speed and alternately delivering them at separated positions, together with means for forwarding the cigarettes from said separated positions at reduced speed. In the best constructions, said mechanism includes two coacting belts running over fixed and movable pulleys. Preferably, means are provided for oscillating these coacting folding belts, which means, in the best form contemplated, consists of a slide supporting the movable pulleys and eccentric actuated means for reciprocating said slide.

The above means may be widely varied in construction within the, scope of the claims, for the particular structure selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention therefore is not to be restricted to the precise details of the structure shown and described. Referring to the drawings, the device se lected for illustration is shown arranged to cooperate with the usual cigarette rod cutoff mechanism of a cigarette machine. Secured to the frame- 6 of the cigarette machine is a bracket 7 carrying the cutoff mechanismJ This bracket carries the main drive shaft 8 on which the rotating element 9 of the cutoff is supported. At its forward end the shaft 8 is provided with a gear 10 meshing with a gear 11 attached to a shaft 12 in the bracket 7. Concentric with the shaft 8 this bracket 7 supports a stationary gear 13 with which gear 14 of the cutoff meshes, thereby reciprocating the cutoff blade 15 by means, the details of which are notshown because not a part of the present invention. The other end of the shaft 12 carries the gear 16 driving through gear 17 the shaft 18 journaled at 19, which shaft serves as the drive shaft of the several parts of the ciga- .oscillate the forwarding belts. brought about by mounting these studs on a rette collecting mechanism. Coo rating with the cutoff blade is the usua led r plate 21, reciprocating on bar 22, provi ed with a guide tube 20 out of which the severed cigarettes emerge.

As the cigarettes emerge from the tube,

at a speed slightly greater than that of the cigarette rod to thereby separate the cigarettes as they are forwarded. The studs 28 carrying the stationary pulleys are mounted in housings 31 and 32 fastened to studs 33 on the frame 6. Helical gears 34 mounted on the studs 28 mesh with gears 35 and 36 on the shaft 37, which shaft is connected by coupling 38 to the shaft 39in the bracket 40, this latter shaft being driven through gears 4 1 and 42 from the drive shaft 18.

lng-oiderto alternately deliver the ciga- ,rates rammed by the belts and 6 at 56 arated positions, the studs carrying t e movable idle pulleys 29 are reciprocated to This is slide 43 moving in a guideway 44 supported by an arm 45, this slide being operated by a link 46 from an eccentric 47 on the drive shaft 18. The pulleys 27 and 29 of the belt 26 are adjustable toward and away from each other,

to grip cigarettes with the desired firmness. This is done by moving the housing 32 on studs 33 to adjust one of the pulleys 27 and by shiftin stud 30 in block 43 to adjust one of the pulleys 29.

The alternate cigarettes thus delivered at separated positions are forwarded at reduced speed, preferably about one-half of that'of the belts 25 and 26, by the laterally spaced belts 48 and49. At this reduced speed the cigarettes maybe abruptl stopped for transverse delivery as hereina ter described, without injury. The belts 48 and 49 run over pulleys 50 -51 and 50-52 respectively, the pulley 50 bein a double one mounted on and driven by shaft 53 journaled at 54 on the arm 45. This shaft is coupled at 55 to a shaft 56 journaled at 57 and driven by means of gears 58 and 59 from the shaft 18. The idle pulleys 51 and 52 mounted on shafts 60 and 61 respectively are supported by the bracket 62 from the cigarette machine frame 6 and the upper runs of the belts 48 and 49 are supported by a plate 63 having upstanding walls 64, 65, and 66 which extend along the sides of the belts and retainthe cigarettes thereon. Plate 63 is suitably supported by the bracket 62 and by an angle piece 67. At the delivery end of each of the belts 48 and 49, curved deflecting plates 68 and 69 roll the cigarettes sidewise out of the path of the succeeding cigarettes and transversely extending walls 79 and 80 in the path of the cigarettes halt their longitudinal movement. The cigarettes from each of the belts 48 and 49 are received from the deflecting plates on the delivery belts 70 and 71 respectively, on which they are arranged side by side ready for removal and packaging. These belts are suitably driven by a drum 72 on a shaft 73 journaled in brackets 74 and 75 and driven from a shaft of the cigarette machine. The deflecting plates 68 and 69 are suitably supported by angle pieces 76 and 77 and a brace 78.

It will be seen that since alternate cigarettes only are received on each of the forwarding belts 48 and 49, the cigarettes need only be forwarded at a little more than onehalf of the speed at which they are. delivered from the cutoff. At this speed there is no danger of injuring the ends of the cigarettes when their longitudinal movement is halted and their rebound will be under sufficient control so that proper alignment and grouping on the deliver belts will not be interfered with. Also, since alternate cigarettes only are grouped on each of the delivery belts 70 and 71, tipped cigarettes which emerge from the cutoff with their tipped portions adjacent, will be delivered onto each belt with all of the tips on each belt pointing in the same direction.
